PILING AND REMOVING MACHINERY FOR COAL.

SPECIFICATION forming part of Letters Patent No. 453,966, dated June 9,1891.

Application filed February 8, 1891- Serial No. 380,462- (No model.)

To aZZ whom it may concern:

Be it known that I, JAMES M. DODGE, a citizen of the United States, anda resident of Philadelphia, Pennsylvania, have invented certainImprovements in Piling and Removing Machinery for Coal and AnalogousMaterial, of which the following is a specification.

Myinvention relates to apparatus whereby coal or analogous material ispiled in large storage-heaps, and is removed as required by a conveyerwhich attacks the pile at the base and is free to move transversely, theobject of my invention being to permit of the action of said removingdevice throughout an area within which is contained the entire base ofthe pile, so that said pile can be completely removed. This object Iattain by means of a special construction of piler and a specialconstruction and location of the remover in respect thereto.

In the accompanying drawings, Figure 1 is a side view illustrating myinvention, and Fig. 2 is a plan view.

Heretofore in coal-handling machinery of this character the pilingapparatus was so constructed as to form an obstruction for the freepassage of the removing-trough or conveyer completely under thestructure. Consequently only a portion of the coal could be removed bythe trough, the remainder of the coal having to be shoveled or otherwiseconveyed into the path of the trough or removed independently thereof.This necessitated a great loss of time and added greatly to the expenseof handling the material. By my present invention I form a shear havinglegs A A, which completely span the formed pile of coal or othermaterial, On one of the legs of the sheers is the conveyer B, of anysuitable construction, for carrying the material up to form the pile.This conveying apparatus, as well as the form of truss, is fully setforth in my patent, No. 446,814, dated February 17, 1891, and thereforeneed not be described in detail in this present application. Adjacent tothe sheers of the piling machinery is the removing-trough D, which inthe present instance is pivoted at d, and isof such proportions as toswing freely under the sheers to remove the coal thereunder, as clearlyshown in Fig. 2. This trough is provided with a suitable conveyer whichmoves in the direction of the len gth of the troughto carry the materialto the pivot-point, from which point it is distributed as required. Inthe present instance it is carried up the incline plane B and loaded incars or boats, as the case may be. The conveyers of both the piling andremoving apparatus are driven in the present instance from the sameengine or from the same line-shafting.

In Fig. 2 I have shown a double removingtrough situated between twopiling structures and so arranged as to swing freely under bothstructures. This is the most economical method pf building a plant, asone removing-trough can be used for two piling structures.

I claim as my invention The combination, in an apparatus for removing orpiling coal or analogous material, of the sheers of the piling apparatusspanning the pile of the material, with a horizontallymovable conveyingtrough and a conveyer thereon for removing the material from the pile,the arrangement of parts being such that the removing-trough can passfreely under the sheers of the piling apparatus to remove the coal piledthereunder, substantially as set forth.

In testimony whereof I have signed my name to this specification in thepresenceof two subscribing witnesses.
